l To all 'whom t may concern:

. in such'manner as to enable the driver of tov start a gasolene motor.

the machineto charge or prime the combustion-chamber of the motorpreparatory to cranking or starting the motor.-

By experiment and observation it has been ascertained that in atemperature of forty degrees and upward it is not troublesome Betweensaid and the freezing pointthe trouble increases rapidly and the primingof the carbureter is helpful, but it is necessary to spin the startingcrank a number 'of times in order to obtain an ex-f plosion. Belowtwenty-degrees, unless'the motor is kept in a warm place, or heatedwater is introduced into .the radiator and circulating system of themotor, the problem of starting the Iengine under average circumstancesis a diiiicult one to solve. A iushed carbureter does not produce therequired vapor and feeding gasolene through the spark plugf hole is atedious and `trying operation. v

By means of the device hereinafter particularly described, the motor maybe easily started at any time in a temperature down to or below zero, asby priming the motor in a manner hereinafter described, the enginestarts easily and `in nearly every in stance an explosionis eHected by asingle turn of the starting crank. A

To the above end, the invention consists inthe novel construction,combination, and arrangement of parts, as vhereinafter more fullyldescribed, illustrated and claimed.

IThe primer contemplated yin this invention and which is applicable'toVany motor car, at any convenient point onthe` car, where it is readilyaccessible to the driver, comprises a reservoir adapted to contain asup'- plyI of gasolene.l This reservoir comprises an outer. cylindricalmetal shell 1, a cap 2 threaded upon the'upper end of said shell,`

upon the lower end of said a'base 3 threaded shell, and1 an. insideglass cylinder 4 Awhich is held in place by the shell and between .the

The shell 1 isfenestrated -or provi ded 'at opposite pomts with observationopenings orwindows: 6 to enable the driver 'to notel whether or not there isasutlicient quantity of `gasolene dontainedin the reservoir,

This air passage alwaysremains open so that air may pass into the'reservoir to, supply thespace previously occupied by the g'asolene' allowing thev gasole'ne toflow freely from the reservoir for or extension 18' a purpose herey te'rof a.turn,.stop pins 23are mounted on inafter set forth. .As anadditional means -for holding the cock closed,` a cock clos ing spring19 has one end; secured to the cap 2as` shown at 20,-the other endcarrying a ring or collar 21 which encircles the stem `9 and isfastened' thereto by means of a -screw 22 orits equivalent, 'thetension.l of

said spring 19 ybeing exerted in.- a downward 'direction on the cock 10.In order to adapt the handle to be swung through a quarl a glasscylinder 26 which is fitted therein like the cylinder 4- 4abovedescribed so 'as to obtain la liquid and. air `tight construction. Ahollow 'tube-l 26 extends' from the charge chamber intofthe reservoir toa point near the top thereofandacts as an airvent for thechargemhamber'. v

The -lower end ofLthe charge measuring chamber 24 isy enlarged 4.andinternally 'Y' threaded as shownat 27 to fit .upon a threadwithacorrespondingpassage 33 ada ted toed boss or extension 28 on the upperside of a priming cock casing 29, the latter being provided Withavertical passage 30 extending therethrough. rlhe priming cock A'31 is ofthe tapered plug type and is providedvat oneend with an operating handle32 and at a point in line with the passage 30 be'moved into and out ofline with t e pas'- sage 30. The priming cock is-also provided .with anoblique or inclined passage 34. adapted to be moved into andoutofregister with an air .inlet passage 35 inthe casing4 29,-,the outerend of said air inlet passage being protected by adust protector or hood36 which is secured to the casing' 29.,by means of a screw'orequivalentfastening device -37 the projecting end of the hoo overlying an oriiceof the air inlet and excluding dust, dirt and other. foreign matterwhile allowing air to be readily sucked into said passage.I The primingcock 31 is also 38 a. apted -to come in contact with corre# spondingIpins or shoulders 39 on the casing 29 to limit the turning movement ofthe.

handle 30 to ninety degrees.I Communicating with the passage 30 is apriming tube 40 which leads to the mixture intake pipe, communicatingvtherewith at a point between the carburetor and the combustion chamberof the motor or engine and in this way an admixture of airand gasoleneis delivered into the intakey pipe at 'the point mentionedy rovlded witha stop pin or shoulder lwhereupon it is drawn ,by the suction lof thecombustion into the combustion chamber of the motor.l The gasolene fromthe reservoir 1 passes through the L-shaped passage 41 in the taperedlower end of the reservoir cock 10 and is thereby discharged into themeasuring chamber 24 when the cock 10 is drawn into the properdirection, the base 3 being provided with a radial port 42 with whichsaid passage 41 communicates when the cock 10 is turned to the properpoint. v

- Thecasing 29 of the priming cock is oonnected rigidly to a supportingbase or bracket 43 provided with a iiange 44 formed lwith holes 45 toreceive screws or other v:fasteners by means of which the device, as awhole, may be connected to the dash or other convenient part of themotor car, said bracket supporting the entire priming device hereinabovedescribed. The upper end of the'airpassage 16 shown in Fig. 1 may alsobe extended laterally or' horizontally as shown at 47 in Fig. 6 in orderto prevent any dust, dirt or other foreign matter from falling into said.air inlet and finding its' way into the reservoir.

ln operation, the reservoir 1 being partly .or wholly filled withgasolene andthe prim? ing cock 31 being closed, the operator,preparatory to starting the motor, opens the reservoir cock 10 andallows the same to remain open long enough to fill the charge measuringchamber with gasolene. He then closes the cock 10 after which he opensthe .priming cock 31 which allows the supply .of gasolene together withair drawn in throughv the passages 35 and 34 to be conducted by gravityto the mixture intake pipe of the motor between the carbureter and thecom bustion chamber. A single turn of the start-4 ing crank will thusyobtain an explosion which will effect an initial starting of the engine,after which the engine will-maintain itself in operation.
